Assessment of Chesapeake Logperch Movements
In order to successfully reintroduce these fish into their former range, we must understand the movement within and between streams and determine if the behavior of released cultured fish differs from transplanted wild fish. We propose to use Passive Implant Transponder (PIT) tag technology to trace the movement of both cultured and transplanted fish. We have successfully cultured the Chesapeake Logperch in our facilities and will hold some 200 fish over the winter, so we will have adult fish to implant the electronic tags. We will install two grids above and below the release site in Chiques Creek. These arrays can detect the tags. We will release a minimum of 100 cultured fish between the arrays. At the same time, we collected wild fish from West Branch of Octoraro Creek and tagged and released these fish at the same release site at the same time. The technology permits us to identify individual fish so we were able to determine if they moved upstream or downstream during the summer and be able to differentiate movement of cultured and tagged fish. Additionally, we sampled the area where they were released with seines each month to enumerate the presence of any tagged fish, which did not move out of the area. The purpose of this study was to 1) track the movements of both cultured and wild populations of spawning Chesapeake Logperch; 2. determine if cultured fish exhibit the same life history patterns of wild-caught fish; and 3) determine the time spent in tributaries.
